Clacks , Crunches, or cant get Neutral

Took mine in this morning as planned.

Bahnstormer had a BMW tech come in today to look at another bike (unrelated) and he took mine for a test ride.

He apparently agrees that 'something' isn't right and has authorised Bahnstormer to do a full strip down of my clutch.

Bahnstormer are being very good, sorting me a loaner etc.

Will keep you posted.

Had mine back to the dealer today due to poor 1-2.... 2-3 gear change.

Service manager said mine was the only one they'd had back with this problem.
Technician said it wasn't the worst one he'd come across. :nenau

Anyhow the service manager advised me that they had spoken to BMW technical support who are aware of this problem and currently working on a fix.
A report will be sent to BMW regarding my bike and I will be contacted when a fix is sorted.

Mine is the other bike down south. The bike will have the new push rod fitted this Thursday. I was told that they had success in Germany with the new push rod. Well we will see.

48 hours from now you and I should know, we might just let everyone one else know the results, if they're nice to us!!! ;)
 
At 3000 miles my gearbox has slowly improved to the point where most changes after 1st are usually snicking in. There is still a random factor to it and occasionally a change clunks. I sometimes seem to anticipate the clunk before it happens, but I haven't been able to consciously work out what the factor is that causes it.

14k bike there should be no clunks,whether it's random or not if it does it it's not right.

I'd seen an argument made that the clunks were as a result of a particular balance being chosen between lever force required and the clutch design, and hence the level of clunk was a deliberate compromise. In other words a smoother change would produce a stiffer hand lever.

Dunno why then some bikes seem to have a better feel, but equally a stiff clutch was what I used to hate about the Ducati 916. And that was a 15k bike a decade ago.

Surely you're not suggesting the WC was designed for the limp wristed?..........

I have just seen the new push rod, which will be fitted to my bike tomorrow.
The old push rod had two bearing surfaces on it. I guess that they run in a phosphor-bronze bearing. The new rod has grooves within the bearing surfaces and reduced diameter between the two bearing surfaces thus it should allow more oil to pass between the clutch plates. So it appears that this problem might be caused by oil starvation between the clutch plates.

Just got home from a whole day spent getting this new pushrod and yet another clutch fitted.
I spent the whole 30mile journey home trying to get smooth changes up and down. Unfortunately the news isn't good. Gear changes are still random. Some smooth then one catches 2 or 3 cogs before going in, with no reason why. The down changes are still consistently bad, crunchy and unpleasant.
The kick back through the gear lever is still the same annoyance either up or down the box, when it throws a bad change.
Whatever this fix was, it made some up changes smooth as you could ask for, but it hasn't fixed the main problem.
I thought when I first rode it again that it was much better, but as it warmed up and the miles went by, it got almost as bad as it had been.
I took the new 800 Adventure out for a test ride today and apart from a very vibey engine I really enjoyed it. Thing was, apart from a good old clunk into 1st the gears were as smooth as silk, I didn't think about them after the first minutes and just got on with enjoying the bike. Can't say the same for my ride home.:tears
 
Sorry to hear that Wyreflyer, I to have spent the day wondering about my bike, I'm still not happy new clutch is about thousand miles in, its now OK at neutral selection, but today I was being following by a IAM Observer and being video'd at same time, It made me focus on my riding, I had some hefty old cluncks n clacks, it was putting me off riding smoothly in traffic, in the lower gears.

I'm waiting for 6k service I'm now at 5k, It's getting to the stage when I book it in I will say I'm not happy fix it or replace it.
 
Got mine back from Bahnstormer yesterday.

Before stripping down the clutch they checked the fluid levels and found the clutch fluids to be overfull.

They pulled some out and hey presto - everything is much better.

Seems that's the complete opposite of BMW's thinking, new pushrod was to get more oil to clutch, as mine is running dry :confused:
 
Seems K1600 owners have gone through the same thing and it's taken 2 years to rectify.

From the K1600 section on this forum.

"BMW K1600 Transmission Recall

There is about to be a total recall of the older k1600’s that have the older defective gearboxes.


23007721500 - TRANSMISSION

23007721500 was superseded by 23008531100.

- There is a new part number for the transmission (complete assembly).

My dealer has been denying that there is a problem with the transmission in my K1600 for over a year.

But once I gave him the new Transmission part number along with the court decision from New Zealand everything changed.
Within three weeks I had a full replacement transmission in my bike.

And guess what? NO TRANSMISSION CLUNKING!!!!!!

Here is the link to the court decision in New Zealand:

A result at last."

Mine was hydraulic oil that was overfilled rather than engine oil.

You might want to get them to check.

Southport just called, can I call in tomorrow, they want to try reducing the hydraulic fluid level. Spooky or are they following this?!!! :eek:

Well, if a BMW dealer has any pretentions at customer care and knowing what his customers and potential customers are saying, then he bloody well should have someone detailed to read websites such as this. So well done BMW Southport if they are acting on what they have seen written

Anyone technical on here? How would reducing the reservoir level help?
Click to expand...

I honestly can't believe it will make a hapeth of difference. The reservoir is just that a reservoir of fluid to top up active system if it needs it,

A good example is as your brake pads wear the amount of fluid in the brake system needs to increase to take up the slack in the system.

Generally in a hydraulic clutch the fluid requirement decreases as clutch wears...the mechanical system gets bigger - opsite of brakes.

So what effect removing some of the fluid will have puzzles me..
